What are the different types of JC Chemistry tuition classes available at your centre?

We have 3 modes of learning for students to choose from: weekly physical classes at Bishan; weekly online lessons via Zoom; and on-demand video lessons.

Are you the only Chemistry tutor conducting the classes or do you engage other tutors to do that?

Please be rest assured that I conduct all my classes personally and I do not engage other tutors to teach at my centre.

How well do your students perform after attending your H2 Chemistry tuition classes?

Most of my students showed improvements by at least 3 grades and more than 80% have attained distinction for A Levels. The earlier the students join my classes, the more confident I am in improving their grades.

What is your class size at Bishan?

Usually the class size is around 10 to 12 students. Max class size is 16 pax.

Is there makeup lesson if I miss a class?

Yes makeup lesson is available in the same week subject to availability. If makeup class is not possible, the student can view the recorded video lessons at Google Classroom.

Do you have trial lesson available? How much is it?

Yes we do. Fees for trial lesson are for Bishan class and for Zoom online class.

Does your centre offer O Level chemistry tuition? Do you teach IB / IP chemistry tuition? How about H1 Chemistry?

Chemistry Guru specialises in H2 Chemistry for JC1 and JC2 or IP Year 5 and IP Year 6 students only. Find out all the information about A Level H2 Chemistry and the detailed comparison between H1 and H2 Chemistry. We do not conduct lessons for H1 Chemistry, O Level Chemistry, IB Chemistry or IP Chemistry at IP Year 3 and IP Year 4.

Amine, Phenylamine or Aniline and Amide Reactions - Organic Chem

In this video we go through the 3 Must-Know Amine reactions, 3 Must-Know Phenylamine or Aniline reactions and 3 Must-Know Amide reactions.

Must-Know Amine Reaction:

1. Neutralisation reaction of amine to form ammonium salt using dilute sulphuric acid at room temperature

neutralisation of amine to form ammonium

2. Nucleophilic substitution of primary amine to form secondary amine using chloroalkane in ethanol, heat in sealed tube

nucleophilic substitution of primary amine to form secondary amine

3. Condensation of amine to form amide using acid chloride at room temperature

condensation of amine to form amide

Must-Know Phenylamine or Aniline Reaction:

1. Neutralisation reaction of phenylamine to form phenylammonium salt using dilute sulphuric acid at room temperature

neutralisation of phenylamine to form phenylammonium

2. Electrophilic substitution of phenylamine to form 2-bromophenylamine and 4-bromophenylamine using Br₂ in organic solvent

electrophilic substitution of phenylamine to form monosubstituted products

3. Electrophilic substitution of phenylamine to form 2,4,6-tribromophenylamine using aqueous Br₂ at room temperature

electrophilic substitution of phenylamine to form trisubstituted products

Must-Know Amide Reaction:

1. Acidic hydrolysis of amide to form carboxylic acid and ammonium salt using dilute sulphuric acid, heat or reflux

acidic hydrolysis of amide

2. Alkaline hydrolysis of amide to form salt of carboxylic acid and ammonia or amine using dilute sodium hydroxide, heat or reflux

alkaline hydrolysis of amide

3. Reduction of amide to form amine using lithium aluminium hydride in dry ether, followed by water at room temperature

reduction of amide

Memorising the reagents and conditions for these nitrogen compound reactions is an integral part of Organic Chemistry, so I've added a short memory test.

Let's see if you can remember all of them!
